What is the default load balancing algorithm set in an SD-WAN Forwarding Profile?

The default load balancing algorithm set in an SD-WAN Forwarding Profile is Weighted Round Robin (WRR). This algorithm assigns weights to each path based on the available bandwidth on the access circuit. WRR is recommended when paths with equal priorities are provisioned with different bandwidths, ensuring that traffic is distributed proportionally to the bandwidth of each path, which optimizes the utilization of network resources and maintains load balancing across the WAN circuits​​.
